Builders and contractors now have a new fastening solution with the launch of SPAX composite deck screws, a new addition to the family of SPAX Engineered Fasteners and the SPAX Deck Solution Center category of products. 

“We know deck and outdoor living spaces continue to be a priority for our customers and end-users,” said Robert Yates, SPAX associate product manager. “Whether using traditional wood or low- maintenance composite decking, builders now have more SPAX® fastener options – and colors - to get the job done right.”

SPAX composite deck screws are engineered with an undercut head to prevent mushrooming and provide a clean finish into PVC, capstock, and composite deck boards. They come in seven colors to match common composite deck board shades. A color-matching tool on the SPAX website allows users to match the SPAX composite deck screw to the color of their deck.


SPAX composite deck screws also include the following features:

  • Reverse upper thread clears away excess material
  • T20 T-star drive for positive bit engagement
  • Ideal fastener length for use with 1” and 2” nominal thickness boards
  • Type 17 double slash point for a fast start and to prevent splitting
  • HCR coating that is IRC/IBC code compliant for use in treated lumber and exterior exposure condition 3 (general construction)
  • Tri-lobe shank to prevent cracking or splitting of deck boards
